Employee and workforce portals — HR self-service, payroll, scheduling, training, expense, time-and-attendance — are usually hosted by a third-party SaaS provider (Workday, UKG/Kronos, Dayforce, ADP, UltiPro, SuccessFactors, Oracle HCM, SAP SuccessFactors, PeopleSoft) on behalf of the employer. Below are 0 guides covering workforce portals across many employers. Each "official site" link points to the public-facing entry the employer asks staff to use — checked manually.
Most workforce portals will not work if you visit the SaaS provider's generic login (for example, a bare workday.com page); you need the employer's tenant URL, which usually includes the employer name as a subdomain or path. The employer's HR team is the right person to ask for that URL if you do not have it written down — not the SaaS provider's support line.
If you have just started or just left
New hires often cannot log in for the first 24–72 hours; the account is created on the employer's payroll cycle, not at signing. Former staff can usually keep access to W-2s, pay history, and benefit information for a year or more — there is normally a "Former employee" or "Alumni" login link on the same portal, sometimes requiring last-paycheque details to set a new password.
